*ELASH-LIGH'I'L To allwhom it may concern: V

Be it known that I, AooLrH O. BECKER, a citizenof the United States, residing at Oakville, in the county of Litchfield and State of Connecticut, have i'nventeda new and. useful Improvement in Flash-Lights; and I do hereby declare the following, when taken in connection with the accompanying.

drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, in- I Figure 1' a side view of a flash light'constructed in accordance with my invention. Fig. 2 a side view partly in section, at a right angle to the position shown in Fig.

1. Fig. 3a broken sectional view of the bottom portion of the lamp with the cap partially screwed on. Fig. 4; an end view with the cap removed.

This invention relates to an improvement in flash lights'of the portable type, and particularly to flash lights having round casings. To hold the. batteries in place and compensate for slight variations in length, it has been, customary to insert a spring in the bottom of the cap which is applied to the lower end of the case which spring bears upon the lower end of the battery.

The object of this invention is to employ a spring at this point which will serve not only to providefor varying lengths of batterms, but will become one of the terminals and be permanently connected with the case; and the invention consists in the construction hereinafter described and particularly recited in the claims. 1 V

In carr in out my invention, I employ the usua tu ular case 4: containing the usual incandescent lamp, not shown, which is secured in place by a collar 5 screwed .onto the upper end of the case'and holding the usual magnifying lens 6. The lower end of the case is closed by a cap 7 in substantially the usual way except in the cap is located a disk 8 of insulating material.

The usual battery 9' is employed, which is inserted into the case the upper end being in contact with the lamp. The lower end is'engaged by a spring 10 hinged to a strap 11 riveted to the side wall. of the case but insulated therefrom, the upper end 12 of the strap extending into the path of movespecification 6f teete s ratent.

ment of aswitchplate 13 which is provided wlth a button or finger-piece 14 extending outward through a slot 15 formed in a housing 16 secured to the case. The spring 10 is formed from a piece of wire'doubled in the center around which central portion 17 the end of the strap 11 is folded so as to hinge the spring to the strap. The ends of the wire then extend substantially parallel to a point-ap roaching the opposite wall of move away from the side of the casing and hold that strap out of contact with the side wall of the case. The spring is readily. folded outward to give clearance for the entrance or removal of the batter When the cap 7 is screwed into place ,t e spring is insulated from the case until the switch) Patented se t. 19, 1916. y Application filed June 19, 1916.

3. A flash light comprising a tubular metallic casing, a strap secured to the sidewall of the casing and insulated therefrom and extending to the lower end thereof, a spring hinged to the lower end of the strap, said spring formed with cam-surfaces adapted to bear upon a battery, a cap closing the 'lower end of the casing and tending to crowd the spring intothe casing, and means end of the casing, a spring hinged to the for closing the circuit from the upper end lower end of said strap the ends of the said of the strap to the casing. spring formed with cam-surfaces ada ted 4.
